产品介绍 A8508 Features and Benefits
• Eight integrated high current sinks for LED strings; can be tied together for even higher currents • Fixed frequency current mode control with integrated gate driver / boost controller; powerful gate driver to drive an external N-channel MOSFET allows significant scaling capability on the number of LEDs per string • Parallel operation capability with one boost controller (master) and up to three additional slave controllers; can run up to 32 strings of LEDs while populating only a single master boost regulator • Active current sharing between LED strings for 0.7% accuracy and 0.8% matching • Wide input voltage range: 9 to 40 V • Internal bias supply for single-supply operation (typically VIN = 12 or 24 V) • Fset / Sync function to either set the boost converter switching frequency or synchronize at up to 800 kHz • Protection Features ▫ Open or shorted LED pin protection ▫ Open Schottky protection ▫ Pulse-by-pulse current limit ▫ Overtemperature protection (OTP) |
